2 GSP-1620 Modem Overview The QUALCOMM Globalstar GSP-1620 Satellite Data Modem delivers reliable digital data communications wherever Globalstar data service is available, using QUALCOMM’s patented CDMA technology and the Globalstar Communications System’s constellation of 48 low-Earth-orbit (LEO) satellites. Figure 2-1 depicts a conceptual overview of the Globalstar GSP-1620 Modem, including its ports and antenna.
GSP-1620 Modem Overview The GSP-1620 modem is a bare board “sandwich” stack of Circuit Card Assemblies (CCA) containing two boards: • Globalstar RF board — includes the LNA, RF power amp, upconverters and downconverters, TCXO, synthesizers, and the remaining power electronics. • Globalstar Digital board — includes the processor, the modem, and some of the power management electronics.
GSP-1620 Modem Product Specification Packet and Asynchronous Data Service The GSP-1620 modem handles two kinds of data connections: • Packet — over the Internet or other TCP/IP packet-switched network • Asynchronous — routed through the Public Switched Telephone Network (PSTN) to a destination modem Figure 2-2 depicts a typical use of the GSP-1620 modem for a Supervisory Control and Data Acquisition (SCADA) application using packet data.
GSP-1620 Modem Overview Figure 2-3 depicts a typical use of the GSP-1620 modem for a SCADA application using asynchronous data.
GSP-1620 Modem Product Specification interfaces facilitate ease of use and OEM application integration. Note • The SCADA application serves as the DTE (data terminating equipment, or terminal) at the remote site, communicating with software in the modem through AT commands sent to either the modem’s Control or Data ports. • Data flows to and from the modem over-the-air, using the Globalstar satellites and Gateways connected to the Internet (for packet data) or to the PSTN (for asynchronous data).
GSP-1620 Modem Overview Table 2-1 lists some typical Remote Monitoring and Supervisory Control and Data Acquisition (SCADA) applications. Table 2-1.
GSP-1620 Modem Product Specification ❑ Remote substations. ❑ Capacitor bank monitors. ❑ Voltage regulators. ❑ Pole-top Remote Termination Unit (RTU). ❑ Load management. Oil and Gas Wells, Tanks, Pipelines, Offshore Platforms For oil and gas wells, tanks, pipelines, and offshore platforms, a SCADA application using the GSP-1620 modem could perform many tasks, for example: 80-99240-1 Rev. D • Monitor pipeline cathodic protection rectifiers to ensure operability.
GSP-1620 Modem Overview Water Treatment Plants For water treatment plants, a SCADA application using the GSP-1620 modem could perform many tasks, for example: 2-8 • Monitor water flow along pipelines and achieve better regulation of water pressure, thereby reducing unnecessary consumption and eliminating water loss. • Reduce maintenance costs by detecting lift station failures. • Monitor waterways and canals.
GSP-1620 Modem Product Specification Remote Inventory Management For managing remote inventory, a SCADA application using the GSP-1620 modem could perform many tasks, for example: • Receive remote inventory information that can be reviewed in real time by procurement, logistics, production, transportation, sales and suppliers. • Streamline inventory management with remotely monitored information delivered in real time. • Eliminate stock-outs, shortages, and stockpiling.
GSP-1620 Modem Overview Remote Banking and Retail Transactions For remote banking and retail transactions, a SCADA application using the GSP-1620 modem could perform many tasks, for example: • Set up banking ATMs in remote areas with reliable and cost-effective Globalstar communications, without dependency on unreliable or expensive terrestrial communication lines. • Transmit credit card verification and remote retail authorization transactions. • Monitor performance and inventory of vending machines.
3 Features This chapter discusses key features of the GSP-1620 modem, including the following: • General modem features • Packet/asynchronous data overview • Packet data service • Asynchronous data service General Modem Features The general features discussed in this section work with either packet data or asynchronous data. For packet-specific features, see Packet Data Service on page 3-7. For asynchronous-specific features, see Asynchronous Data Service on page 3-11.
Features AT Commands The GSP-1620 modem can be controlled using standard AT (modem attention) commands, which are listed in Chapter 4. Modes of Operation The GSP-1620 modem has two serial ports: one for Data and one for Control. The modem can be set up to use the Data port only or both the Data and the Control ports. • If solely the Data port is used, AT commands can be sent to the modem only when there is no data session active.
GSP-1620 Modem Product Specification The SMS feature is fully functional even if the GSP-1620 modem is active on a data call, because SMS can be accessed on the Control port. Therefore, the host application can send command and control information to the modem either while it is in a data session, or idle (not in a call). The SMS feature may not be available on all Gateways.
Features SMS AT Commands The GSP-1620 modem can use the following SMS commands: • Navigate through SMS messages (AT$QCSMSM). • Delete SMS messages (AT$QCSMSM). • Print/display current SMS message ( AT$QCSMSP). • Lock or unlock SMS messages (AT$QCSMSL). • Turn on/off SMS alerting (AT$QCSMSA). • Get information on SMS messages stored in memory (AT$QCSMSI). For more information, see Table 4-1 on page 4-1.
GSP-1620 Modem Product Specification Service Status Message The AT$QCSTATUS command gets the Service Status Message, which you can think of as a message detailing the information that would display on the LCD screen of the GSP-1600 Tri-Mode Phone.
Features Packet/Asynchronous Data Overview The GSP-1620 modem handles both packet and asynchronous data connections. For a particular SCADA application, one may make more sense than the other. QUALCOMM Globalstar packet data service has a lower overhead and faster connection time than asynchronous data does. In general, if a SCADA application does not specifically need asynchronous data, it should use packet data instead. Table 3-1 compares the two types of data. Table 3-1. Packet vs.
GSP-1620 Modem Product Specification For more details about the two types of data service, see Packet Data Service on page 3-7 and Asynchronous Data Service on page 3-11. Packet Data Service Globalstar and the GSP-1620 modem offer direct Internet connectivity by bridging the “last thousand mile” air gap using LEO satellites. This section details the capabilities offered by the GSP-1620 modem for user connectivity and packet data transmission.
Features When developing embedded SCADA applications, developers can use off-the-shelf protocol stacks or write their own. Any standard RFC 1661 or RFC 1662 compliant stack should work. Interoperability with Different Operating Systems The GSP-1620 modem uses standard networking software to establish, manage, and tear down the PPP session.
GSP-1620 Modem Product Specification no mobility is involved, and the user’s application requires a fixed IP address, then a fixed IP addressing scheme should be used. The difference is that in a “fixed” addressing scheme the user’s application at a host site or server will always know the IP address of the remote DTE (SCADA application). In a “dynamic” addressing scheme, the IP address is not known until the remote SCADA application/modem and the host/server are in an active session.
Features Note In the first Gateway software release that supports modems, fixed IP addressing requires that private IP addresses be “decoded” from the modem’s IMSI (International Mobile Subscriber Identity). This precludes the use of fixed IP addressing with roaming between Gateways. Virtual Private Network Service Since a fixed IP addressing scheme requires the use of private IP addresses, a virtual private network or VPN (e.g.
GSP-1620 Modem Product Specification For packet data service, roaming operation has the following characteristics: • Roaming within a Gateway service area can keep the PPP session up the entire time, using dormant mode. • Roaming between Gateway service areas is supported. However, there is no hard hand-off capability between separate Gateways. The PPP session will be dropped and will have to be reestablished by the modem.

GSP-1620 Modem Product Specification Data Rate and Throughput For asynchronous data, the GSP-1620 modem offers full duplex transmit and receive at a Data port rate of somewhat less than packet data’s 9600 bps, due to additional overhead for asynchronous data. Similarly, the measured effective “user” throughput (that is, customer data) is somewhat less than the 7400 bps (average) for packet data. Asynchronous connections take longer because of PSTN modem training time.
Features • Roaming within a Gateway service area is supported for both mobile-originated and mobile-terminated asynchronous data calls. • Roaming between Gateway service areas is supported; however, if the modem is in a call when it reaches the edge of a service area, the call will be dropped and must be re-established on the new Gateway. • Once on a new Gateway, automatic re-registration will be performed and a new data call can be established.
4 AT Commands The AT (modem attention) command set is the control interface between the SCADA application (Data Terminal Equipment or DTE) and the GSP-1620 modem (Data Communications Equipment or DCE). This chapter lists the AT commands that apply to the QUALCOMM Globalstar GSP-1620 Satellite Data Modem: • Table 4-1, “Operational AT Commands” — lists the AT commands recognized by the modem software.

5 Hardware Description This chapter describes the QUALCOMM Globalstar GSP-1620 Satellite Data Modem hardware, including mechanical descriptions of the modem, antenna specifications, user interfaces, and grounding. Modem Mechanical Description The GSP-1620 modem is a sandwich made of two circuit card assemblies (CCAs) that are open and unprotected. As a result, the GSP-1620 modem must be shielded from direct impacts, precipitation, and particulates.

Hardware Description Modem Dimensions and Weight Modem dimensions are 190 x 75 x 17 millimeters (7.48 x 2.95 x 0.68 inches). Modem weight is less than 180 grams (6.3 ounces). Modem Antenna Connectors The GSP-1620 modem has two (2) MCX snap-in connectors for the antenna leads, connecting the DRA to the modem: Caution • Transmit (Tx) lead is labeled J3. • Receive (Rx) lead is labeled J7. The MCX connectors are secured only by a solder joint and are not designed to withstand excessive force.
GSP-1620 Modem Product Specification Note The modem signal naming convention assumes that the modem is the DCE and that the user application is the DTE. DTR/DSR Signal and Power On/Off An active DTR on any of the three serial ports (Data, Control or Diagnostic) turns on the GSP-1620 modem (if DC power is applied first). The modem then boots up from the shut-down state and asserts DSR to indicate that it is booted up and ready to communicate.
Hardware Description modem alerting, and SMS messages to be sent simultaneously via a separate “control” port to/from the modem. This separation of functionality is especially useful in dormant mode, when the application and host sessions are active, and thus the Data port appears active/in use, although a Globalstar traffic channel is not up (no “In Call Status Message”). The Control port is “enabled” by asserting DTR on the Control port.
GSP-1620 Modem Product Specification DB-25 Data and Control Port Pinouts Table 5-1 provides detailed information about the Interface connector pinouts. Table 5-1.

This line should be left floating for normal modem operation.
Hardware Description Note • POWER for an active translator Diagnostic cable • PROGRAM to enable programming of the modem Normal field usage does not require that a cable be connected to the Diagnostic port on the modem, since that port is typically used for development and programming only. DC Power The GSP-1620 modem requires input DC power ranging from 5.6 V to 16 V, with 1 Amp (maximum).
GSP-1620 Modem Product Specification Caution OEMs must ensure that the output impedance of the power supply sourcing DC power to the modem is always less than that of the input impedance of the modem. Otherwise, a potential exists for oscillations on the DC power line and the GSP-1620 modem will not operate as designed. Surge Protection OEMs are responsible for ensuring that the input voltage specification will never be exceeded.
Hardware Description Power Consumption Power consumption depends on a variety of factors such as transmit power, input voltage, and data rate. Table 5-2 summarizes the power consumption of the GSP-1620 modem at an input voltage of +12 V DC. All power estimates include the DC power consumption of the ODU’s receive section. Table 5-2. Modem DC Power Consumption Estimates at 12 V DC Input Mode Minimum Typical Maximum Shutdown 1.2 mW 2.4 mW 6 mW Standby 280 mW 500 mW 2.4 W Transmit 3.6 W 4.
GSP-1620 Modem Product Specification Note At least one port DTR signal must remain asserted during the entire power-on sequence, until a DSR signal is asserted. Power-Off Power-off is also controlled via the OR’d DTR signals. When all port DTRs have been de-asserted for a minimum of one second, the GSP-1620 modem begins its power-down sequence. After all software processing has concluded, the modem powers off.
Hardware Description Grounding The GSP-1620 modem has been designed to provide flexibility in the area of grounding, with options to make connections between digital ground and the OEM-provided chassis ground (metallic enclosures). These grounding options are also independently available for the DB-25 user interface, Diagnostic port, and associated cable shields. The GSP-1620 modem has been certified in accordance with the technical and regulatory requirements of the FCC and the European Union.
GSP-1620 Modem Product Specification OEM Installation of the GSP-1620 Modem QUALCOMM offers the GSP-1620 modem without a mechanical enclosure, anticipating that OEMs will integrate and package the modem into an enclosure or cabinet appropriate to the end-user’s application. The enclosure must shield the GSP-1620 modem from direct impacts, precipitation, vibration, acoustic noise, and particulates. The GSP-1620 modem has six mounting holes sized for M3 screws.
Hardware Description Note • Do not fasten the modem with enough clamping force to damage the printed circuit board. • Exercise caution and do not damage components on the modem during handling. The GSP-1620 modem meets or exceeds all operational vibration requirements defined in Table 6-1 on page 6-4 when E-A-R damping feet (MF-100-UC04-H, black) are used as shock mounts.

D • The required connectors are plug SMA (DRA bulkhead) to plug MCX (modem). • Transmit cable maximum 0.6 dB insertion loss @ 1618 MHz is required for the cable. • Receive cable maximum 3.
Hardware Description QUALCOMM does not provide cables for OEM bulk applications since OEMs may need cables of different lengths for particular applications. Table 5-3 lists potential suppliers of RF and microwave connectors and cable assemblies. Table 5-3.

GSP-1620 Modem Product Specification Calculating Antenna Cable Length The maximum loss for an antenna cable of any length is 0.6 dB at 1.6 GHz for modem transmit and 3 dB at 2.5 GHz for modem receive. OEMs must take these losses into account when calculating antenna lengths for a GSP-1620 modem installation. For example, the GSP-1620 Modem Integrator’s Kit utilizes three feet of LMR 195 cable, which has a loss of 0.6 dB at 1.6 GHz.

Irvine, CA 92612-1073 Tel: 800/272-7537 Fax: 949/851-2127 Parker part number: 2-137 E515-80 Description: O-ring, ethylene-propylene, 2.050 inches diameter by 0.103 inch thick, 80 durometer When mounting the antenna on rough surfaces, surfaces which have already suffered significant environmental damage (pitting, peeling paint, etc.), or surfaces that are not sufficiently flat, it is recommended that an O-ring not be used.
GSP-1620 Modem Product Specification Mounting Multiple Antennas If required for the application, OEMs can mount multiple antennas within several feet of each other without creating significant interference. QUALCOMM testing has determined that if two antennas are placed near each other and transmit on different frequencies, only a barely perceptible (1 dB or less) increase in 1605 emission occurs when tested at full jamming power. This maps to isolation between antennas of 20 dB.
